摘要

支氣管內過誤瘤被認為是來自支氣管內結締組織的罕見肺部良性腫瘤。本病例是一位64歲男性患者，主述於住院前一個月開始有咳嗽及氣促的現象，痰液為灰白色，偶而併有血絲。胸部X光顯示患者有左上肺葉塌陷的現象。支氣管鏡檢查，發現左上肺葉開口被表面平滑呈分葉狀的節結所阻塞，其切片檢查的病理報告為被慢性發炎細胞所浸潤的支氣管黏膜。由於肺部電腦斷層攝影顯示節結內含有脂肪組織及鈣化物，術前診斷為支氣管內過誤瘤。患者隨後接受袖式肺葉切除術。
支氣管內過誤瘤的臨床症狀和支氣管阻塞有關。胸部X光的表現及支氣管鏡檢查的發現都不具特殊性。電腦斷層攝影因為較容易發現腫瘤中的脂肪組織及鈣化物，提高了支氣管內過誤瘤的術前正確診斷率。

Endobronchial hamartoma is a rare benign tumor arising in the bronchial wall. We present a 64-year-old male patient who suffered from cough with bloody sputum and dyspnea. Chest X-ray revealed atelectasis of the upper left lobe. The gross bronchoscopic finding was that the orifice of the upper left lobe was obstructed totally by a lobulated nodule with a smooth surface, and the bronchoscopic biopsy showed chronic inflammatory mucosa. Due to the finding of fat tissue and calcification in the nodule on CT, an endobronchial hamartoma was diagnosed preoperatively. Later, the patient underwent a sleeve-lobectomy resection, without incident.
The symptons of endobronchial hamartoma are related to bronchial obstruction. The findings on the chest X-ray and bronchoscopy are nonspecific. Because CT can effectively detect the characteristic findings of fat tissue and calcification in the endobronchial hamartoma, an accurate diagnosis becomes possible preoperatively.
